Bedridden for too long body pain chills and want to vomit and lower extremity venous thrombosis, cerebral hypoxia, osteoporosis, gastrointestinal slowing of peristalsis and other reasons related to the need to follow the doctor’s instructions for anticoagulation, thrombolysis, oxygen, pain, promote gastrointestinal dynamics of the cause of the treatment. 1. Lower extremity venous thrombosis: After lying in bed for too long, because of the slowing down of blood flow and the reduction of blood circulation, thrombosis is easy to occur, especially lower extremity venous thrombosis. Patients may have lower limb pain, swelling, even with fever, chills, vomiting, indifference and other systemic manifestations, need to follow the doctor’s instructions for anticoagulation, thrombolytic therapy, and if necessary, surgical removal of thrombus treatment. 2. Cerebral hypoxia: prolonged bed rest can lead to slowing down of blood flow, thus the ability of blood to carry oxygen will be reduced, the brain is in a state of hypoxia, which can lead to abdominal, chest and other generalized pain, fainting, vomiting and even shock and other symptoms, which need timely treatment such as oxygenation, expansion of blood volume and other treatments. 3. Osteoporosis: long-term bedridden, easy to induce osteoporosis, the emergence of generalized bone pain, coupled with a lack of activity, gastrointestinal peristalsis slowed down, resulting in gastrointestinal dysfunction, nausea and vomiting symptoms, according to the cause of the need for pain, supplemental calcium, to promote gastrointestinal dynamics, acid suppression and other treatments. There are many other reasons for the pain and chills caused by staying in bed for too long, so it is recommended to consult a doctor in time to clarify the cause of the disease and carry out targeted treatment to avoid delaying the condition.
